Step-by-step explanation:
Marx would critique the American system of slavery for exploiting the labor of enslaved individuals and perpetuating class divisions. According to Marx, capitalism is driven by the desire of the bourgeoisie to exploit the labor of the working class in order to accumulate wealth and maintain political power. The American system of slavery fits into this critique as it allowed the slave-owning class to profit from the forced labor of enslaved individuals while keeping them in subjugation and perpetuating social and economic inequalities.
